5.9.4. Diving at altitude
The dive computer can be adjusted both for diving at altitude and also to increase the
conservatism of the mathematical nitrogen model.
When programming the instrument for the correct altitude, you need to select the
correct Altitude Adjustment settings according to Table 5.6, Altitude Adjustment settings.
The dive computer will adjust its mathematical model according to the entered altitude
setting, giving shorter no-decompression times at higher altitudes.
For more information, see Section 10.2.3. Altitude diving.
